Definitions

  • a DC power supply bus including two power supply lines is connected upstream to a DC voltage source, e.g. photovoltaic panels or a battery, and downstream to a controlled inverter for generating a variable voltage with an electrical load.
  • a filtering solution is used for controlling the voltage variations present at the input.
  • one or more filtering capacitors are connected to the first power supply line and the second power supply line of the bus.
  • the total capacitance of the capacitors must be sufficient to absorb the input voltage ripples.
  • the capacitors are often of the chemical type and have a large space requirement, are expensive and have a limited life span. To overcome these drawbacks, active filtering systems have been provided.
  • the switching assembly includes:
  • FIG. 2 represents an electronic diagram of an example of embodiment of the active filtering system of the invention
  • the switching assembly comprises a first transistor T 1 and a second transistor T 2 .
  • the second transistor T 2 is connected to the second terminal B 2 of the switching assembly SW and to the first transistor T 1 . It also comprises an inductor L 1 connected both to the first terminal B 1 of the switching assembly and to the midpoint located between the two transistors T 1 , T 2 . It also comprises a capacitor C 2 , designated the second capacitor, connected to the first transistor T 1 and to the second terminal B 2 of the switching assembly SW.
  • the assembly formed by the two transistors T 1 , T 2 and the inductor L 1 operates as a power amplifier used to generate the voltage V AF intended to compensate for the AC component ⁇ tilde over (V) ⁇ C1 of the voltage V C1 at the terminals of the first capacitor C 1 .
  • the second capacitor C 2 is used to create an electrical potential V AUX with respect to the second power supply line 11 of the DC bus for supplying the power amplifier of the switching assembly SW.
  • the role of the second capacitor C 2 is notably to absorb the variation in power and to limit the variation in the potential Vaux.
  • the power amplifier may comprise a capacitor C 3 , designated the third capacitor which, in collaboration with the inductor L 1 , smooths the voltage V AF generated by the switching of the two transistors T 1 , T 2 .
  • This third capacitor C 3 is connected between the first terminal B 1 and the second terminal B 2 of the switching assembly SW.
  • the transistors T 1 , T 2 are dimensioned to withstand the voltage Vaux.
  • the voltage Vaux may be in the order of 1/20 th of the voltage Vdc of the DC power supply bus.
  • the switching assembly formed by the transistors T 1 , T 2 and the inductor L 1 are dimensioned for supporting a current of the order of the peak value of the AC component of the load current.
  • FIG. 4 represents a variant embodiment of the switching assembly SW used in the active filtering system AF of the invention.
  • the switching assembly SW comprises two additional transistors T 3 , T 4 connected in parallel with the second capacitor C 2 .
  • the second terminal B 2 of the switching assembly SW is no longer connected to the second capacitor C 2 and to the second transistor T 2 but to the midpoint located between the two transistors T 3 , T 4 .
  • the third capacitor C 3 may be provided and connected between the first terminal B 1 and the second terminal B 2 .
  • This second topology is notably used to reduce the voltage V AUX applied to the second capacitor C 2 and can be used for generating an AC voltage, in replacement of the DC power supply bus.
